PATCH 1/2 ASoC: arizona: Add debug prints for output power up/down times

When debugging it is useful to check the total power up/down delay that is executed as part of the coalesced output delay. This patch adds some debug prints for this.

PATCH 2/2 ASoC: arizona: Add output power up/down delays for speaker path

The later Arizona parts do run write sequences to power up and down the speaker path as such a delay needs to be inserted into the DAPM sequence to allow this to run. This patch adds appropriate delays into the existing coalesced delay scheme.

Applied "ASoC: arizona: Add output power up/down delays for speaker path" to the asoc tree

The patch

ASoC: arizona: Add output power up/down delays for speaker path

has been applied to the asoc tree at

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks,
Mark
